to provide such a; chair which iscom'fortable and convenient in use, relatively simplein mechanical construction and reasonably economical in manufacture.

' An illustrative embodiment of the invention is I spective" positions in instances wherein a person seeks ingress to'or egress from another chair in thesame row of chairs and past such occupied chair; a i r Figure 4 is an enlarged,- fragmentary side elevational view of the chair, partly in vertical section, and'showing its seat and back in their respective positions of normal occupancy of the chair;

A horizontally disposed sheet metal i plate I6 1 is supported along its opposite ends upon" the upper edges ofthe brackets M to whichit is secured and the plate has an integrally formed dependingor flanged portion ll engaging the'for- T ward edges ofeach bracket.

A pair of C-shaped links 21 are each pivotally connected at one of their ends between a pair of spacedbell crank levers l8, l9 m'edi'ally'of each and each C-shaped link is pivotally connected short of its other end in an inverted channel member 28 whose other endspare each pivotally' connected to a rod 30 onwhich an upholstered seat 3| is supported.

The opposite sides of the-seat3l are each provided with an outwardlyprojectingtongue 10i secured substantially medially of the length of the seat in any suitable manner, which 'itongues each rest upon the upper side of a channel member 28 when the seat'is in occupied position.

The free end of each C-shaped link 21 is provided with a yoke and a roller 32 disposed between the arms of each yoke rides upon the upper surface of the forward end of its proximate seat supporting arm 25 during the movement of the seat 3| and back 26 from their respective positions shown in Figure 4 to their positions shown in Figure 6.

Stops 33 and 34 "secured to the opposite sides of each inverted Y-shaped link respectively engage bumpers 35 and 36 of rubber or the like disposed between the pair of spaced bell crank levers I8, I 9 and between the pair of spaced links 20, 21 for limiting the forward-rearward movement-of the seat 3| and to provide for noiseless "movement.

It will thus be seen that the chair herein shown and described provides forr'a'dy andcom venient egress from and ingress to unoccupied seats in the same row of seats without seriously disturbing the occupant cream a chair orthe boeupant of a chair immediately rearwardl y th""" of.
